The dynamic changes in the absorption coefficient of water as a function of incident fluence at 2.94, 9.6 and 10.6 micrometer was quantified. The Q-switched Er:YAG laser and a TEA carbon dioxide laser were used to measure the transmission across precisely measured water layers of varying thicknesses. The measured data was used to develop a dynamic, finite-difference absorption model to predict the spatially and temporally varying absorption coefficient of water.
